Dyes for polymer coloration, their preparation and their use

ABSTRACT

The present invention relates to a compound of formula (I), where A and B are each as defined in claim  1 , to its preparation and to its use.

Polymers can be colored with dyes in various ways. One way is mass coloration of polymers whereby for example a pigment or a dye is mixed with the polymer and the polymer is melted to transport the dye into the polymer matrix. Other processes involve the polymer being colored, or to be more precise dyed, by the dyes diffusing into the polymer from a solution or dispersion, examples being the dyeing of polymeric fibers composed of polyester, polyacrylonitrile, polyurethane, cellulose or polyamide for example with, for example, disperse dyes, cationic dyes, acid dyes, metallized dyes or reactive dyes. The use of reactive dyes results in a covalent bond being performed between the dye and the substrate, conferring particularly high fastnesses on the dyeings/colorations. Another way to color a polymer is to add the dye to the polymer's monomers or oligomers, before the polymer is formed or as it is being formed. Dyes capable of forming covalent bonds with the polymer scaffold may likewise result in colorations of high fastness being obtained. For this, the dyes used, or to be more precise their chromophores, have to be sufficiently stable under the conditions of the polymerization.

Commercially available pigments when used in mass coloration of polymers do give colored polymers of predominantly high fastnesses, but the colorations are dull, i.e., lack transparency. Commercially available dyes for polymers are usually disperse dyes or solvent dyes and produce, when used for the coloration of polymers, colored polymers in which the dye often only has low bleed fastnesses. In addition, many of the known dyes have poor lightfastnesses or low thermal stabilities. In polyolefins, Dyes having good bleed fastnesses, good lightfastnesses, good thermal stabilities as well as high saturation and transparency in polyolefins without adversely affecting the properties of the polyolefins used are not known in large numbers. EP 0 006 122 A1 discloses perylene dyes which meet the above-recited requirements only in part since they are not suitable when high bleed and wet gap fastnesses are desired.

EP 0 283 436 A2 describes perylenediimides having aliphatic radicals containing carboxy and/or carbamoyl groups attached to both nitrogen atoms. These dyes do give good results in the coloration of polyolefins, but there continues to be a broad need for improvements, for example with regard to the transparency of the colorations or the thermal stability of the colorations.

JP 2006098927, JP 10006645, US2007/0221913A1 and WO2007/099059 A1 and also J. Phys. Chem. B., 3.Juli 2008, 112, Supporting Information, S1-S13, J. Org. Chem. 2005, 70, 8956-8962 and Chem. Mater. 1998, 10, 3603-3610 also already describe perylene dyes having poly(oxy)alkyl chains, but do not disclose their use for polymer coloration.

There is therefore a need for dyes which have the recited properties and thus are useful for the coloration of polyolefins.

It has now been found that, surprisingly, perylenetetracarboxylic diimides having a specific substitution pattern for the imido groups represent useful dyes for the coloration of polyolefins and other substrates. They have high stability under application conditions, are readily soluble in the polymer, or miscible with suitable organic solvents, and afford highly transparent colorations having high bleed fastness.

Suitable catalysts are quinoline, piperazine, pyridine, picolines or heavy metal salts, preferably zinc salts, most preferably zinc acetate.

The compound of formula (VI) is known and can be prepared by following methods known in the literature, for example as described in Dyes and Pigments, (4) 1983, 171 ff.

The compounds of formulae (III) and (IV) are likewise known and commercially available or obtainable by following known methods.

Preferred compounds of formula (IV) are the compounds sold by Huntsman, The Woodlands, Tex., USA under the brand name of Jeffamine®. Examples are Jeffamine M-600, Jeffamine M-2005, Jeffamine M-2070, Jeffamine M-1000, Jeffamine D-230, Jeffamine D-400, Jeffamine D-2000, Jeffamine D-4000, Jeffamine HK-511, Jeffamine ED-600, Jeffamine ED-900, Jeffamine ED-2003, Jeffamine ED-2001, Jeffamine EDR-148, Jeffamine EDR-176, Jeffamine T-403, Jeffamine M-3000, Jeffamine T-5000, Jeffamine XTJ-435 and Jeffamine XTJ-436. When these compounds are used, the resulting dyes of formula (I) form statistical polymeric mixtures.

After synthesis, the dyes of formula (I) can be isolated by filtration, extraction or evaporation and, if necessary, drying. However, they can also be used without further workup.

The dyes of formula (I) according to the present invention can be used directly for polymer coloration, or they are subjected to a finishing (conditioning) operation to convert them into a salable dye preparation.

Finishing can be effected proceeding from a single dye of formula (I) or from a mixture of two or more dyes of formula (I) or mixtures of one or more of the dyes of formula (I) and dyes of other dye classes, for example pigments or solvent dyes, if appropriate with the assistance of auxiliaries, for example surface modifiers and dispersants, by dispersing, suspending or dissolving in a liquid or solid carrier material and also if appropriate standardizing to a desired color strength and a desired hue and if appropriate drying the preparation thus obtained.

Preparations comprising dyes of formula (I) may further comprise auxiliaries for modifying viscosity/flowability.

Useful auxiliaries of this kind are described for example in U.S. Pat. No. 6,605,126. Preferred examples are ethylene glycols, propylene glycols, polyether polyols, polyester polyols, lactones and carbonic esters.

The present invention accordingly also provides dye preparations comprising one or more dyes of formula (I) and also one or more auxiliaries for modifying viscosity/flowability.

These dye preparations preferably contain one or more dyes of formula (I) in amounts of 5% to 100% by weight and one or more auxiliaries for modifying viscosity/flowability in amounts of 0% to 95% by weight, all based on the dye preparation.

The present invention further provides for the use of the dyes of formula (I) according to the present invention for coloring a polymer.

A possible procedure here is for the dyes of formula (I) to be admixed to the polymer. In addition, dyes of formula (I) according to the present invention can also be used in the form of masterbatches. Masterbatches are dye concentrates consisting of carrier materials and colorants, the colorants being present in higher concentration than in the final use and the carrier materials being constituted such that they have compatibility with the materials to be colored. The carrier materials used can be polymers, for example polyolefins, polyurethane, polyvinyl chloride, polyesters, polyamides, polycarbonates or polystyrene. Preferred polymers are polyolefins, for example polyethylene or polypropylene and copolymers with polyolefins. Useful carrier materials further include paraffin oils and polyglycols. The dye masterbatches are characterized in particular in that they contain one or more dyes of formula (I) according to the present invention in amounts of 5% to 60% by weight and one or more carrier materials in amounts of 40% to 95% by weight.

The dyes of formula (I) have advantages in bleed/migration fastness in polyolefin mass coloration in particular, compared with commercially available solvent dyes. These advantages are particularly noticeable in the coloration of polypropylene, polypropylene copolymers and polypropylene blends. To achieve good bleed fastnesses for the colored polymer, it is preferable to use compounds of formula (I) that have sufficiently high molar mass.

The examples hereinbelow serve to elucidate the invention without restricting the invention to these examples. Parts and percentages are by weight, unless otherwise stated. Parts by weight relate to parts by volume as the kilogram relates to the liter.
